I have the cheapy thermometer -the mercury kind-that came with my hovabator 1602N that says its 110+ and then I have an expensive one that tells me humidity which is at 49% -the time of day-which doesnt matter-and the temperature which it says 100.2-5 all the time. The temp on that has been steady for the past 3 days-I never really payed attention to the cheapy one until this am..they were both in the same spot laying partly on there sides next to the turner-Im on day 6 now-
